A few years ago, commercial motherboard CPU and IPC motherboard CPU difference between not obvious, causing some businesses use commercial motherboard CPU as industrial control board CPU to maximize profit to gain more profit.The gap between them is increasing, mainly in the following areas:
1. CPU power consumption and processing
Industrial control motherboards generally use low-power CPUs to adapt to harsh environmental applications in the industrial control industry. Prior to the AtomN270 CPU , Intel did not have a dedicated embedded department, only industrial control as a general-purpose CPU application industry. Since the embedded department was established in 2009 , Intel has released AtomN 230 , N 270 , N 280 and other low-power CPUs to distinguish between commercial CPUs and industrial control CPUs .
2.Differences in the ability to resist electromagnetic interference
Due to the market positioning and good use environment of ordinary commercial motherboards, their products only undergo commercial electromagnetic compatibility tests, and their ability to resist electromagnetic interference is low.
3.The circuit design of the CPU
Since the motherboard needs to adapt to a wide temperature and voltage industrial application environment, the touch screen industrial control computer motherboard has a wider voltage adaptation range than commercial motherboards. The voltage range of industrial control motherboards is generally between 9 and 20V . In the circuit layout and design of the CPU , it is required to be more accurate.
